Datasets.
We use the standard sentence-level RE datasets: TACRED [1]}, SemEval-2010 Task 8 [2]}, and TACREV [3]} for evaluation.
TACRED contains over 106k mention pairs drawn from the yearly TAC KBP challenge.
SemEval does not provide entity type annotations, for which we only construct the topic caches for message passing.
[3]} relabeled the development and test sets of TACRED to build TACREV.
The statistics of these datasets are shown in tab:data.
We follow [1]} to use F1-micro as the evaluation metric.
